T0 all whom t may concern Be it known that l, R101-Iam) M. Benam, a citizen ot the United States, anda resident of Brooklyn, county ot Kings, and State ot New York, have invented a new and useful lmprovement in rlypographical lrlachines, ot which the following is a speciiication.

lily invention relates to typographical machines, such as linotype machines ot the general organization represented in Letters l3nt ent ot the United States, No. 436,532, to O. ll/lergenthaler, wherein circulating matrices are .released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the tace ot mold, the mold iilled with molten. metal to i'orm a slug or linotype against the matrices which produce the type characters thereon, and the natriees thereafter returned through a distributing; mechanism to the magazine from which they started.

ln the lltlergenthaler patent above men tioned, the distributing devices comprise rotatinp,` screws to convey the matrices Valong a grooved rail or bar, from which they are released at the proper points to return them to the appropriate channels in the magazine, and my invention is herein set forth in connection with that specific mechanism. Ob viously, however, the principles thereol:l are capable of broader application, and may be adapted to distinctly different styles ot distributing` devices, as well. as to other forms of typographical machines, such tor instance as those handling type or dies instead et matrices. Generally speaking, l desire it to be understood that l do not limit myself to any specific form or embodiment, except in so liar as such limitations are specified in the claims.

A principal feature of my invention is a special means tor arresting the driving mechanism in the event that the operation of the distributing devices is checked or retarded, which feature generically speaking is not novel. For instance, in the applica tion for Letters Patent ot elohn Rogers, Serial No. 687,691, iiled April l, 1912, stop devices are illustrated, wherein is employed a member termed with cam faces and a pin or stud to contact therewith, in the event ot some derangement of the parts which renders it essential or desirable to arrest the distriloutici5,A mechanism, auch contact effect inn' the disengagement ot the driving clutch. ln the said application, a single cam member is employed and it is shown specifically as formed with tour cani Jraces, the result ot' this construction beinev the possibility oi a quarter revolution of the operating, means heitere its final arrest. ln order to reduce the extent ci such operation alter the tripping ot the stop devices, l propose to use a plurality thereojlE arranged in different re lation to the dri vingl mechanism, so that the latter will be checked at additional points in the cycle of operation. lier this purpose, l preferably employ al plurality oi2 cam inembers, mounted so that the cam faces of one are alternated or staggered in relation to those of another, and in connection with each of them a pin or stud to engage therewith. For instance, in place ofthesingle cam .member having` :tour taces, l have illustrated two cam members each having eight faces, which as previously mentioned are relatively staggered or alternated, and it will he seen that the rotation possible after the tripping oi the stop devices is thus re duced from a quarter to one-sizrteenth- It will be understood, ot ecru-se, that the particular arrangement referred to is shown simply by way oil example, and that the principle may be ent-ended to any extent desired, either by employing a lai-,eer nlnnber ot stop devices, or by increasing the number ot cam faces in each, or both.

ln the accompailying;V drawing: Figure l is a transverse section through the operating,` means for the distributino,` mechanism, l1av ingr my invention applied thereto; and Fig. 2 is a front view of the same, partly broken away and partly in section.`

rl`he distributor screw il is rotated in the customary manner from a chain oi gearing', con'iprising` the gear ll immediately connected to the screw, which chain receives its motion from the band wheel C, sleeve D, sprocket gearing ld, El, ctc. 'llhe specilic arrangement of gearing; is unessential to the 'presentinvention, and is or may be oit' any desired torni, such l'or instance as illustrated in the Rogers application previously re terred to. rlhe B is mounted upon the screw i in such manner as to be capable of a partial rotation thereon, this being;` secured in the torni shown by the en sagement ot the pin .fil on the screw in the inclined slot "B1 in the huh et the The gear ll norm mally pressed outwardly or toward the left by the projection F1 on the lever F, pivoted at F2 to the machine frame and forced outwardly by the spring F3 connected to the opposite end thereof. It is this spring pressure that holds the gear B in its normal relation to the screw A, namely, with the pin A1 at the lower end of the inclined slot B1, the strength of the spring being sufficient to maintain the relation in ordinary operation. When, however, the rotationbf the screw is checked or retarded, as for instance by the engagement therewith of an arrested matrix, the gear B continues to rotate with respect to the screw, the effect of this relative movement being also to shift the gear Alaterally or inwardly thereon, due to the outward travel of the pin A1 in the inclined slot B1.

The sleeve D is provided with the friction clutch surface D1, which is normally held in engagement with the wheel C by the pressure of the spring D2. The arrest of the driving means is effected by the movement of the sleeve D inthe opposite direction against the force of the spring D1, thereby interrupting the frictional engagement referred to. 'Ihe lateral movement of the gear B previously described is availed of to effect this disconnection.

The sleeve D carries two cam members K, K, formed with laterally inclined faces K1, K1, and in connection with each of these members I provide a pivoted stop arm J, vcarrying a stud or pin L located in position to be projected into the path of a cam face K1. In the drawing, the parts are shown in normal or operative position, namely, with the abutments H, H, of the stop arms J, J,

resting upon the flanges G1, G1, of the projection G connected to the upper end of the lever F. In this relation, the spring F3 holds not only the flanges G1, G1 under the abutments H, H, and consequently the pins or studs L out of the path of the cam members K, K, but also the gear B in its outward and active relation to the screw A. If for any reason the rotation of the screw A be arrested or retarded, the continued rotation of the gear B moves it laterally in the manner previously described, and because of its engagement with the projection F1 on the lever F, the latter is turned about its pivot F2 and against the force of the spring F 3, thereby removing the ianges G1, G1 from their operative position beneath the abutments H, H. The stop arms J, J are thus tripped and their pins L, L proj ected into the paths of the cam faces K1,K1.

In many respects the operation so far described is substantially similar to that of the mechanism old in the art. However, it will be noted that two cam members K, K, and cooperating stop arms J, J are employed, and that the cam faces K1 of one set are staggered or alternated with relation' to those of the other set, the practical effect of which arrangement is to double the number of points at which the mechanism may be arrested. This duplication of the cam members is of particular importance and advantage, in view of the fact that it gives a materially larger number of stopping points than may be conveniently provided for on a single member, it being noted in this connection that such number is somewhat limited in view of the necessary extent and slope of the cam faces thereon.

Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the United States is as follows:
